Unveiling the Potential: A Paradigm Shift in Energy Reduction at Hindalco Renukoot Alumina Refinery

Abstract

The global alumina refining industry is under growing pressure to adopt eco-conscious practices and to achieve key sustainability goals. In addressing the energy-intensive nature of alumina refining processes, it is vital to reduce the industry’s environmental impact. Hindalco has adopted a comprehensive strategy to promote energy-efficient practices for a greener future. The efforts and initiatives have resulted in reduced energy demand at the Renukoot refinery from 13 to 11.9 GJ/T, mainly through the use of process optimization techniques, data-driven insights, adaptive technologies, energy management practices, and waste heat recovery methods. Collaborating with process engineers, industry experts, and management was crucial to monitor, analyse, and optimize operations. Apart from significant energy reduction, the initiatives led to enhanced economic viability and improved the sustainability credentials of the refinery. By setting a precedent, Hindalco Renukoot can inspire other refineries to follow suit, thereby fostering a more sustainable and eco-friendly alumina refining industry.
